    PR # 32255                                                                   
     We propose to obtain spectra of the massive ( 400 solar masses / yr)        
     cooling flow in the cluster A2597 at z = 0.0824. As well as having          
     one of the larger known mass deposition rates,  the cooling flow in         
     A2597 is a particularly large fraction of the total X-ray luminosity.       
     SIS spectra will determine the column density of absorbing material         
     intrinsic to the cooling flow (providing clear constraints as the           
     galactic column is low), and determine the mass deposition rate and         
     detailed spectral signature of the cooling gas.  SIS and GIS spectra        
     outside the cluster core will determine the elemental abundance and         
     temperature as a function of radius and hence the gas and total mass.
